CHARLES C. WOLFE, OF I-IAYDENVILLE, OHIO, ASSIGNOR 'I'O NATIONAL FIRE PROOFING COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

MECHANISM FOR SURFACING TILES.

To all whom it may concern.-

Be it known that I, CHARLES C. WOLFE, a citizen of the United States, residing at Haydenville, in the county of Hocking and State of Ohio, have invented a new and use ful Improvement in Mechanism for Surfacing Tiles and the like, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an end view embodying my invention;

Fig. 2 is a side view of the same;

Figs. 3 and 4 are, respectively, front and side views of one set of the surfacing members;

Figs. 5 and 6 are,'respectively, front and side views of the other set of surfacing mechanism; and

Fig. 7 is a plan view showing the character of the roughened surface formed by theuse of my invention.

My invention has relation to mechanism of the apparatus for imparting a roughened surface, commonly known as a tex surface to tiles, bricks, etc., of clay or terracotta.

The invention is designed to provide mechanism of this character which can be readily applied to the expressing die of a tile or brick machine, and which will impart to one or more faces of the shaped column of clay issuing therefrom a roughened surface of desirable form.

The nature of my invention will be best understood by reference to the accompanying drawings, in which I have shown a preferred embodiment thereof and which will now be described, it being premised, however, that various changes can be made in the details of construction, arrangement and combination of the several parts without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, the numeral 2 designates the expressing die of a tile or machine of any usual or suitable character. A (Fig. 1) designates the end or sectional shape of one form of tile shaped by said die and which is acted upon by the mechanism comprising the invention.

In the form of my invention illustrated, I have shown surfacing mechanisms for fac- ..ing the top and one side of the issuing clay column. I will first describe the mechanism Specification of Letters Patent.

Patented Sept. 24, 1918. Serial No. 186,889.

for surfacing the upper surface of the clay column.

The numeral 3 designates a bar which is fixedly secured above the path of the clay column a short distance from the mouth of the expressing die 2, and which is provided with a plurality of depending pins or scratching members 4, which are designed to scratch substantially parallel straight lines on the top surface of the clay column. 5 designates another transverse bar having similar scratching members 6, and which is designed to have a reciprocating movement. For this purpose, it is provided with elongated slots 5, which engage the mounting bolts 7, by which it is held. These bolts may be carried by the fixed bar 3. The bar 5 is reciprocated on the bolts 7 by any suitable mechanism, such as the bell crank 8, pivoted at 9 and having an actuating connection 10 with a stud or projection 11 in the central portion of said bar. The other end of the bell crank is connected to a slide block 12 mounted on theslide 13, and actuated by a pitman 14, which is connected to a Wrist or crank pin 15, on a shaft 16, which is driven in any suitable manner, as by a pulley 17. As the shaft 16 is rotated, the bar 5 will have a limited reciprocating movement thereby producing waved scratch lines which loop back and forth across the parallel scratch lines formed by the relatively fixed scratching members, producing the roughened 0r texed surface, substantially as shown in Fig. 7.

A short distance in front of the scratching points, I provide pressing rollers 18, carried by brackets 19, and which are adapted to exert a yielding pressure on the texed surface. Preferably, these rollers consist of a solid body having thereon a layer 18 of cotton or similar cushioning material, with a surface covering 18 of soft leather. A. roll of this character possesses the necessary resiliency and gives the desired light pressure upon the texed surface.

The mechanism for surfacing one side of the clay column is generally similar to that for surfacing the top face of the column, and similar reference characters with the letter a added have been applied to corresponding parts. I have, however, shown a slightly different form of actuating mechanism for the movable scratching bar. In this form, the bar is reoiprocated by means of a pitman 20, connected to the crank or wrist pin of the actuating shaft.

Myinvention can be readily applied to existing die machines of this character by providing suitable brackets, as indicated, on which the parts are mounted and which can be readily secured to the facing plate 21 of the forming machine.

I claim:

1. Surfacing mechanism of the character described, comprising a plurality of fixed scratching members arranged to engage the surface of a clay column, and a plurality of reciprocating scratching members also designed to engage said surface, substantially as described.

2. Surfacing mechanism of the character described, comprising a plurality of fixed scratching members adapted to scratch substantially parallel straight lines in the surface of the moving clay column, and another set of reciprocating scratching members arranged adjacent to the fixed scratching members to scratch waved lines on the surface of said column, together with means for supporting and actuating the movable scratching members, substantially as described.

3. Surfacing mechanism of the character described, comprising a plurality of fixed scratching members adapted to scratch substantially parallel straight lines in the surface of the moving clay column, another set of reciprocating scratching members arranged adjacent to the fixed scratching members to scratch waved lines on the surface of said column, together with means for supporting and actuating the movable scratching member, and a pressing roll adapted to subsequently act upon the scratched surface, substantially as described.

4. Surfacing mechanism of the-character described, comprising a plurality of fixed scratching members adapted to scratch substantially parallel straight lines in the surface of the moving clay column, another set of reciprocating scratching members arranged adjacent to the fixed scratching members to scratch waved lines on the surface of said column, together with means for supporting and actuating the movable scratching member, and a pressing roll adapted to subsequently act upon the scratched surface, said roll having a yielding surface, substantially as described.

5. The combination with the expressing die of a clay Working machine, of surfacing mechanisms arranged to impart a scratched surface to two sides of the column of clay issuing from the expressing die, each of said mechanisms comprising aplurality of relatively fixed scratching points and a plurality of movable scratching points, and means for actuating the movable point-s, substantially as described.

.In testimony whereof, I have hereunto set my hand.
